Sekuyiminyaka ecishe ibe ngu-20, indlela elula futhi efundisayo isetshenziselwe ukutadisha igazi le-utero-placental - doppler fetal. Le ndlela isekelwe emthethweni wokuguqula imvamisa yamagagasi okuvunguza, atholakala ngekhulu le-19 ngumsosayensi wase-Austrian H.I. I-Doppler, futhi isetshenziswe ngempumelelo ekuqaphelisweni kwe-perinatal yabesifazane abakhulelwe.
Iyini i-dopplerometry yesisu?
I-Doppler isifundo sejubane nokuqina kokugeleza kwegazi esibelethweni somama, intambo yomzimba kanye nezitsha zomntwana. Okuyinhloko yale nqubo wukuthi ukuqhuma kwe-ultrasonic okuthunyelwe yi-sensor ye-apparatus kulezicubu kubonakala ku-erythrocytes ehamba ngaphakathi kwezitsha futhi isignali inikezwa ngendlela ye-ultrasound. Kuncike ekuqondeni kokunyakaza kanye nejubane lama-erythrocyte futhi, ngokufanayo, imvamisa yezingcindezi ze-ultrasonic, idivaysi ibhala izinkomba zezibonakaliso. Ngokususelwa ekuhlaziyweni kwale datha, ukuvama kokushintsha kwegazi kuhlelo lomama-placenta-fetus kunqunywa.
Le nqubo ihlukile ekuphenyweni okuvamile kwe-ultrasound ngokuthi ukugeleza kwegazi ezitsheni esikrinini sokuqapha kubonakala ngemibala ehlukahlukene kuye ngokuthi ijubane lokuhamba. Lesi sici sidinga amandla amaningi we-ultrasound, kodwa ungakhathazeki ngokuthi i-doppler iyingozi kumntwana. Lolu cwaningo alulimazi neze kokubili ingane kanye nomama.
Izinkomba ze-doplerometry ye-fetus
I-fetal ultrasound ene-doppler inqunyelwe abesifazane, okukhulelwa kwabo kuhambisane nezifo ezifana nalezi:
- i-gestosis;
- i-pyelonephritis;
- isifo sikashukela mellitus;
- ukungalingani komama nesisu ngeqembu legazi;
- i-hypertension;
- izifo ze-collagen.
Ngaphezu kwalokho, i-doppler yokulalela inhliziyo ye-fetal iboniswa ukungajwayelekile okutholwe yi-ultrasound kanye ne-cardiotocography yesisu. Lokhu kufaka:
- ukubambezeleka kokuthuthukiswa komntwana;
- ukungabi namanzi ;
- ukuvuthwa ngaphambi kwesikhathi ngaphambi kwe-placenta;
- ukuthuthukiswa okungavamile komthamo womlomo;
- ukungafani kahle nosayizi wesisu ngesikhathi sokukhulelwa;
- izifo ze-chromosomal, noma ukusola kwabo.
Lesi sifundo senziwa ekupheleni kokukhulelwa okungenani amasonto angu-20. Ngemuva kwenqubo, udokotela unikeza imiphumela ngokubhalwe phansi kwe-fetal doppler, ekhombisa imigomo noma ukwehluka ekuthuthukiseni ukukhulelwa. Lokhu kuyisifundo esibaluleke kakhulu ngokusizwa okungenzeka kuzo ngezigaba zokuqala ukuthola izifo ezihlukahlukene ze-fetus noma izinkinga emzimbeni womama.
